According to Rob Sellers of CougarsDen.com (giggity), Sims is leaving the program, though exactly why isn’t clear. In a release from the school a short time later, UH said Sims was simply weighing his future options. One thing the release made clear was that Sims has not asked for his release, something he’d have to do if he wished to transfer. Sims has already graduated from Houston and would be eligible to play immediately if he decided that was the route he wanted to go.

“We congratulate Charles on receiving his degree last week and becoming a Cougar for life,” coach Tony Levine said in a statement, adding Sims “has been a leader for our program both on and off field with number of accomplishments.”

Another option for Sims could be the NFL’s supplemental draft in June. Obviously, this is all a bit out of the blue considering he’s just months removed from electing to return to UH for another year.

Wherever he ends up, some team, whether at the college or pro level, is getting an excellent running back. Sims was a first-team All Conference USA selection in 2011 and a second-team selection last season. Despite nagging injuries, he still finished 2012 with 851 yards rushing and six yards per carry — still good enough to lead the team. He’s also a noted pass-catcher and can be a versatile weapon for any offense.

Updated 9:15 p.m. ET: In a statement released to CougarsDen.com, Sims confirmed he is departing Houston. As you’ll read below, what the running back’s future holds still remains unclear.

“It is with regret and deep humbling, that I am ending my playing career at the University of Houston. I have a lot of great memories that I will carry with me forever. I want to thank the University of Houston for allowing the opportunity to be a part of its football program.

I have worked extremely hard while I have been here at U of H and made every attempt to carry myself in a manner that would reflect the utmost integrity upon the school and this program.

I don’t know what my next step will be. I have one more year of eligibility, therefore I may look to play (1) more year of college football or I may enter the NFL Supplemental Draft later this year.

My family and I will continue to discuss my options and we will make a decision in the near future.”
